Qur'an 12:21

وَقَالَ ٱلَّذِى ٱشْتَرَىٰهُ مِن مِّصْرَ لِٱمْرَأَتِهِۦٓ أَكْرِمِى مَثْوَىٰهُ عَسَىٰٓ أَن يَنفَعَنَآ أَوْ نَتَّخِذَهُۥ وَلَدًا ۚ وَكَذَٰلِكَ مَكَّنَّا لِيُوسُفَ فِى ٱلْأَرْضِ وَلِنُعَلِّمَهُۥ مِن تَأْوِيلِ ٱلْأَحَادِيثِ ۚ وَٱللَّهُ غَالِبٌ عَلَىٰٓ أَمْرِهِۦ وَلَـٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ

And he of Egypt who purchased him said unto his wife: Receive him honourably. Perchance he may prove useful to us or we may adopt him as a son. Thus we established Joseph in the land that We might teach him the interpretation of events. And Allah was predominant in His career, but most of mankind know not.
